The purpose of this study was to (1) compare mother-child interactions in three contexts: shared reading with a book in a traditional print format, with an electronic book in a CD-ROM format, and with an electronic book in a video clip format; (2) compare mother-child interactions with a three-year-old and a seven-year-old; and (3) compare children's extra-textual talk during the shared readings. Results indicated mother-child interactions differed in the contexts, with more complex talk evident in the electronic texts. There were differences in mother-child interactions with the two children that seemed contingent on the child's age and experiences. Finally, children's extra-textual talk differed depending on their ages, and these seemed to be context specific. (Contains 5 tables, 3 examples, and 3 figures.)
